I'm the same mate. Between my Plazmaman plenum, ETM manifold, numerous other custom alloy and stainless gear I've had done, and an all signing and dancing $20k welder we've recently ordered in at work... I also have one hell of an appreciation of professional welding skills!

Leigh's welding abilities are in another dimension in comparison to my capabilities.

Good and bad. It wasn't bad as far as first meetings go and considering the number of new things to keep track of and the tame settings in the thing, it didn't do too bad at all.

First run out I blew the manifold to BOV line clean off and discovered that the spring in the BOV is about 16.5-17psi. :D It was doing all the boost control for me :) and we pulled every cooler pipe, hose, clamp and fitting off to chase the boost leak that was none of the above.

With that problem sorted (but with round 2 and 3 qualifiers happening in my absence, I had to make do with a random dial-in for first round eliminations. I thought that an 11.anything would do for the day and so dialed in 12.00. It would only hold about 3psi on the foot brake so it drove off the line again (2.006 60') and with the boost leak fixed went 11.87 @ 120.89mph. The speed was back but the launch was atrocious. The transbrake would have to do for grudge runs soon to come.

I forgot to arm the brake for the next pass so we just wont talk about that, okay? :P

Last pass they had time for was ok. Good burnout, everything ready to go, transbrake to about 8psi and when i let go of the button it just went sideways and spun all through first with me peddling it to get it under control. I should have in-car vid of this pass soon. Slow (11.7 @ 120 - 1.9 60').

That was all we had time for today but will be back soon to revise the launch technique. A 1.60 60' time will see the car in the bottom 11's/high 10's no trouble at the same boost etc. Fingers crossed. :)

Good to catch up with a few people today. Thanks to Elmsy, Macka and Yavuz from Unigroup Engineering for their help.

did u take any data logs? if so what did the oil pressure one look like? (i'm using the same pump/line setup as u on a car i'm building)

Oil pressure was about 60psi when oil up to proper operating temp. That's reading the gauge during the run. Haven't seen logs yet.

One of the best parts of the day was cruising with this guy. Car runs 8.30's on slicks and went 8.60's on radials. Made the 45km cruise and drove through the night from Calder Park to be at the event. (They raced the day before!)

    • Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.
    • Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using. 
    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
